Of 6 persons, respectively suffering from tabes dorsalis, 

 chlorosis, tubercul. pulm. II, tubercul. pulm. I, lues and liver- 

 cancer the sera are investigated in regard to their fibrolytic 

 power. If each serum was diluted 5 times, the dilutions, made 

 from the sera, obtained from persons suffering from tabes dorsalis 

 and chlorosis both proved to be coloured equally strong and 

 strongest of all. Then followed: tubercul. pulm. II, tubercul, 

 pulm. I, lues and liver-cancer. 



The final dilution of each serum, by which fibrine was no 

 longer transformed, was of tabes i : goo ; chlorosis i : 800 ; 

 tubercul. pulm. II i : 600; tuberc. pulm I i : 500; lues 

 I : 450 ; cancer i : 350. Consequently there was a rather satis- 

 fying harmony in the results obtained in both ways. From 

 this series of experiments also appeared already the great indi- 

 vidual variety of the fibrolytic power of the investigated sera. 

 I found this confirmed in all my experiments. 



From these experiments I consequently obtained the following 

 result: The fibrolytic power of human serum is not constant, 

 hut individually shows great variety. I did not succeed at all 

 in finding any fixed rules ; in no state of disease did I find the 

 fibrolytic power constantly increased or decreased. With older 

 people this power mostly seems to be stronger than with youn- 

 ger people. 



ad. 2. In order to be able to answer the question, whether 

 human serum can also transform other albumina instead of 

 fibrine, I used for further consuniing experiments, hen's albumen, 

 lung- and kidney-tissue ; these two last substances, obtained 

 both from a man and a rabbit. (Healthy lungs and kidneys 

 were used). These tissues I again coloured with eosine. Lung- 

 and kidney-tissue, cut into small slices and then put in the 

 colour, absorb much colour, but also lose a great deal of it 

 again through the boiling. Moreover I found that even though 

 the water was quite colourless, the coloured pieces of lung and 

 kidney repeatedly let loose colour when in the controlling-tubes, 

 if they remained in the incubator for i6 hours in a temperature 

 of 37» C. 



The result of the consuming-experiments was, that every 

 human serum that I have searched, corrodes hen^s albumen as 

 well as kidney-tissue.
